As a symbolic act of Sino-American Unity against the pressing dangers of the expanding Japanese Empire, Richard Halliburton (1900-1939), author of The Royal Road to Romance, New Worlds to Conquer, The Flying Carpet, and the two Books of Marvels, attempted to sail a Chinese junk, The Sea Dragon, from Hong Kong to the San Francisco International Exposition on Treasure Island. About 900 miles southeast of Yokohama, the ship with its crew headed into a strong gale of typhoon-like proportions and was never seen again. Biographies of Halliburton include Jonathan Root's Halliburton: The Magnificent Myth (1965) and Gerry Max's Horizon Chasers: The Lives and Adventures of Richard Halliburton and Paul Mooney (2007). See sunflower circle productions regarding recent projects on Richard Halliburton. Both Gerry Max and Carolyn Treanor, CEO of Sunflower Circle Productions, have offered public lectures on the life and legacy of Richard Halliburton, the San Francisco International Exposition, and the History of Travel Writing. Archival materials for Halliburton are housed at Princeton University and at Rhodes College in Memphis where a tower stands to honor his memory.
